My rules:

• Comments: If you comment on one of my MOCs I'll comment on one of yours but only if its a good comment ie. "This is rather good but you could improve some techniques, if you go here you can find some www.examplewebsite.com" would get you a comment but "c00l plz check out my epic m0cs" would definitely not. If you try to do this just to get comments you won't get any.
• Credit: If I post any techniques you want to use, I should have said in the description that you can use it if you give credit. If not just ask and it's likely that I'll say yes] I will always try to give credit to the builders who deserve it but if I forget to give someone credit please tell me and I will update the MOC's page to give the person credit If you use one of my techniques and the technique has its own page, tell me and I'll make a link to it so others can see it in use with other builders' styles
